74VHC157 - QUAD 2 CHANNEL MULTIPLEXER
The 74VHC157 is an high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
It consists of four 2-input digital multiplexers with common select and strobe inputs.
It is a non-inverting multiplexer.
When the STROBE input is he
